ien-CREAM SPOON.

To all whom t may concern.'

Beit known that "I, Josnrrr r vcitizen of the United States, residing at Troy,A county of Rensselaer, and State of New York, have invented certain new 'Y and useful Improvements in Ice-Cream' Spoons, ofw'hich the following is a specification.

Reference may beV had to the accompanying Vdra-wings', and the referenceV characters marked thereon which form a part of this specification. Similar characters refer -to similar parts in the several figures therein; This invention relates to ice-cream spoons, dishers and similar Vdispensing scoop-devices for serving measuredV quantities of plastic material, and having` rotativelymovable cutters or Scrapers v)forV freeing thepla'stic` material Afrom thebcwl, cup or scoop.

The principal objects of the inventionvare to provide a simple and eiiicient operating l mechanism for, the movable `cutter v'or scraper; toconceal from view and protect from Contact with the plastic material substantially all` of the operating mechanism 'for movin@ the cutter `or sera er and to rovide for a more convenient movement A0f, the

Y thumb-piece of the operating mechanism.

Other objects will appear in connection with' the following description. Figure 1 of the drawings is abottom" plan view of an ice-cream 'spoonv embodying my invention.

t `Specifieation of Letters Patent. PatentedNQtni 6, 1917, Appiicrat'oii-meq March 14,1916. serialNmeazia The' semicircularscraper,^4, conforms-t0v the interior of the bowl andfhasprojec'ting cppositely from its respective ends trun nions, 5 andv 6, whereby the scraperisjrotatively mounted coaXially with the shank, 35 of the handle". f Y.

The trunniom 5, on the outer endof the scraper li's rotatively mountedA in a bearing formed by a circular aperture, 7, in the wall of the bowl, and the trunnion,6, is rota# tively mounted in a bearing at 8', in astubular shank, 9,integral with, or in rigid relalv The tubular bowl-shank, 9, is adaptedl for telescopic connectionwith the tubular'shank, 3, ofthe handle. f' i Upon the Outer end of the tubular shank, 3of the handle is fixed a housing, 10, extendadjacent to thegrasp, 2, which housing con tains a bearing, 11, for one end of, the scraper-operating shaft, 12, the otherV end'of which is permanently secured by a rivet, 13,k to a reduced end, 14, of the scraper trun# nion, 6, `whereby rotative movement of the shaft, 12,-is rimparted to the scraper.

yThe shaft, 12, has fixed thereupon adjacent to the bearing, 11, a pinion, 15, adapted to be engaged by. a toothed rack-bar, 16, reciprocatoryI longitudinally within a `chamber, 17, lin the housing, 10,` and guided therein. l y The outerl end of the rack-bar projects from the housing and is provided'with a head orc'thumb-pie'ce, 18, whereby the rackbar 'can be conveniently forced inward by pressure of the vthumb of the same hand byy which the grasp, 2, of the handle is held.

The koutward movement of they rackfbar is limited by engagementof "a screw-head, 19, with ashoulder, 20,'on thehousing, 10.

l* The rack-bar isyieldingly held at the limit at` its outwardmovement by a coil-spring, 21, confined between the screw-head, 19, and a cap, 22, on the adjacent end of the .hous-f inalo.- 1;l The handleeshank, 3, is preferably def ing crosswisev of `the shank of the handle j los by means of a screw, 23, by removal or which screw telescopic separation of the handle-shank from the bowl-shank is permitted, to withdraw from the handle-shank the shaft, 12,A and pinion, 15, as shown in F ig.

The end of the bowl-shank, 9, is partly cut away to form shoulders, 24, in the path of a head, 25, on the rivet, 13, whereby rotative movement of the scraper and scrapershaftis limited in both directions so thatthe scraper is confined in its movement to the space within the bowl.

The relative dimensions of the scrapertrunnion, 6, with its reduced end, 14, and the bowl-shank, 9, are such that the trunnion, 6, can .beinserted from within the bowl through the bowl-shank, 9, in the manner shown .in Fig. 7; and after the trunnion, 8, has been so inserted, the trunnions, 5, can be sprung into its bearing, 7

After the scraper-trunnions have been thus inserted in their bearings, the shaft, 12, is riveted to the reduced end, 11i, of trunnion, 8, thereby retaining the scraper permanently `mounted within the bowl.

I prefer to make the rack-bar circular in cross-section and to have its several teeth extend circumferentially of the bar, as shown, whereby the position of the bar will be constantly changing rotatively in use, thus distributing the wear to different parts of the teeth.

`lVhile I have used the term bowl as applied to a semispherical scoop, I wish it to be understood that consider the various known forms of cup or scoop `used for a similar purpose as the equivalent of the bowl shown; and my improved operating mechanism can be readily adapted for use with cutters or Scrapers corresponding with the form of bowl, cup or scoop employed.

rThe invention is not to be understood as restricted to the details set forth since these may be moded by the skilled mechanic within the scope of the appended claims without departing from the spirit and scope of the invention.
